World's Fastest Supercomputer Can't Run a Day Without Failure

↺ World's Fastest Supercomputer Can't Run a Day Without Failure

> While on paper, the Frontier supercomputer looks exceptionally good, and hardware parts of the machine system have been delivered, it seems like problems with hardware keep chasing the machine from coming online and being available to researchers requiring performance of around 1 FP64 ExaFLOPS.

> “We are working through issues in hardware and making sure that we understand (what they are),” said Justin Whitt, program director for the Oak Ridge Leadership Computing Facility (OLCF), in an interview with InsideHPC (opens in new tab). “You are going to have failures at this scale. Mean time between failure on a system this size is hours, it’s not days.”

Intel Horse Creek platform showcased with SiFive P550 RISC-V CPU, 8GB DDR5, PCIe Gen5 - CNX Software

> When SiFive introduced its Performance P550 64-bit RISC-V processor in 2021, we were told that Intel would use it in the Horse Creek platform with “leading-edge interface IP such as DDR and PCIe” and manufactured with Intel’s 7nm process.

> We now have more details about the Horse Creek platform, as a development board was showcased for the first time in public at the Intel Innovation 2022 Developer Conference, and according to a report by Wikichip, the Cortex-A75 class quad-core RISC-V processor runs at up to 2.2 GHz, supports DDR5-5600 memory and eight PCIe 5.0 lanes, and was taped out with Intel 4 process.

Pine64 Ox64 SBC to feature BL808 64-bit/32-bit RISC-V multi-protocol WiSoC with 64MB built-in RAM - CNX Software

> Pine64 Ox64 is an upcoming single board computer powered by Bouffalo Lab BL808 dual-core 64-bit/32-bit RISC-V processor with up to 64MB embedded RAM, multiple radios for WiFi 4, Bluetooth 5.0, and 802.15.4 (Zigbee), as well as an AI accelerator.

> The board also features up to 16MB XSPI NOR flash, a MicroSD card socket, a USB 2.0 OTG port with support for a 2-lane MIPI CSI camera module, and two 20-pin GPIO headers for expansion. It measures just 51 x 21mm, or in other words, is about the size of a Raspberry Pi Pico W.
